CREATE TABLE "SYS_CODES" ( "HOSPITAL_NO" VARCHAR2(10), "TABLE_NO" NUMBER(6,0), "SUB_TABLE_NO" NUMBER(6,0), "ITEM_NO" NUMBER(6,0), "ITEM_DESC_A" VARCHAR2(100) NOT NULL ENABLE, "ITEM_DESC_E" VARCHAR2(100) NOT NULL ENABLE, "VALUE_1" VARCHAR2(8), "VALUE_2" VARCHAR2(8), "PROTECT" NUMBER(1,0) NOT NULL ENABLE, "LAST_UPDATE_DATE" NUMBER(8,0), "LAST_UPDATE_COUNT" NUMBER(5,0), "LAST_UPDATE_USER" VARCHAR2(8), "LAST_UPDATE_TRANSACTION" VARCHAR2(1), PRIMARY KEY ("HOSPITAL_NO", "TABLE_NO", "SUB_TABLE_NO", "ITEM_NO") USING INDEX ENABLE ) ;I used CASE WHEN before to read ARABIC and ENGLISH names in dynamic menu list and its working why in list of value for page item its give this error when open the page?
